Review: mini review: JBL Synchros S400BT

Stripped down of all its niceties, the JBL Synchros S400BT are a great set of headphones. The sound is full and it hits all the marks no matter what kind of music you toss at it. Comfort was never an issue and the battery life seemed to last longer than it should have. I could go on, and I will later in this review.Once you add in the fine details, along with features like touch control and NFC tap-to-connect functionality, the S400BT seems like the wireless headphones you’ve been waiting for
